Video: 2014 Corvette Stingray Hits the Dyno
Some people get to have all of the fun. First, Edmunds got the initial crack at plopping the SRT Viperon the Dyno and now Chevy is paying a visit to the same folks with its own new model: the 2014 Corvette Stingray with the Z51 package. now you may be thinking "but we already know that the Stingray with the Z51 pack has 460 ponies and 465 pound-feet." You have to remember though, that most cars lose 10 to 20 percent of their power through the drivetrain on its way to the wheels, and the power to the rear wheels is what really matters.
After several tests and plenty of by the guys near the dyno, Edmunds finally rolled out the end result. After several tests, the tester determined that the all-new Corvette Stingray with the Z51 package delivers an average of 411 horsepower and 407 pound-feet of torque to the ground. That’s a respectable 49 horsepower (10 percent) and 58 pound-feet (12 percent) loss through the drivetrain.
What’s more is the interesting power curves that Edmunds pulled from the Stingray. As soon as the exhaust valve opens up around 3,800 rpm, the horsepower number suddenly jumps from about 275 to 290 and the torque jumps from about 370 pound-feet to 390. Additionally, and most importantly, from 2,000 rpm to 6,000 rpm, the Corvette’s torque stays above 300 pound-feet — simply amazing.
